Fix getSnapshotIndexMetaData Exception Behavior (#47488) (#47496) 

If we fail to read the global metadata in a snapshot
we would throw `SnapshotMissingException` but wouldn't
do so for the index metadata.
This is breaking SLM tests at a low rate because they
use `SnapshotMissingException` thrown from snapshot status APIs
to wait for a snapshot being gone.
Also, we should be consistent here in general and not leak the
`NoSuchFileException` to the transport layer for index meta.

Closes #46508
